If I did dip in, I have an atoma 400 (used for flattening) and a spyderco fine stone. I also have a course/fine Arkansas stone.
What would be my next purchase? I was think a atoma 1200 to follow up from the 400 and finish on the spyderco.
Of course this would be to start the learning. Thoughts please.
What kind of steel do you sharpen?
What do you mean with "coarse" Arkansas? A Soft Arkansas or a Washita? Fine is Hard Arkansas?
Diamonds leave deep scratches but work with every steel. So if you are going to sharpen softer steels / low alloy steels mainly, you would not need another diamond plate. You could also use a Japanese stone like Shapton Pro, Imanishi Arashiyama 1.000, a King 1.000 or similiar stones. Or a Fallkniven DC521. One side fine diamond, other side ceramic. Would give you two grits to close the gap between Atoma 400 and Spyderco Fine.
